JQG320t/55m highway bridge-erecting machine

The formation of the single lifing point of travering trolley makes the traversing of edge beam more convenient and direct.

The complete machine of strong front and midle crosbeams and thee crossbeems joints into a rigid integral.The transverse stability of the complete  machine is adequately guaranteed during edge beam erection.Ingenious down-traversing positioning method of girder body makes it unnecessary points eliminate various potential unsafe factors of overhang type traversing track.

JQG320/55m highway bridge-erecting machine researched and developed recently is a large-tonnage-and large-span highwway bridge-erecting machine in China which is a new technical equipment added for domenstic highway & bridge construction.

The main girder itselfis provided with upper travel track,so it is not necessary to pave travel track for overhead travelling crane and longitudinal moving cart,which save customers substantive expensive on auxiliary materials and reduces construction period and economic cost.

Possessing three  innovation technologies right angle,any skew angle,small-radius curve and large-slope dridge,the complete machine operates morre flexibly and conveniently.

The main girder adopts the structure of triangular space truss detached pin-connected main girder to increase the strentgh and rigidity of the complete machine.

The first t realise continuous operation and once for all during the whole bridge-erecting process;one of single bridge-erecting machines with complete functions in the country;adopting walking type complete through-hole so that the complete machine is greatly shortened in length,its deadweight is reduced and the construction load is thus reduced to the maximum extent.
